Gestational diabetes mellitus (GDM) refers to pregnant women with impaired glucose tolerance, which could bring high risk to the mother and fetus. However, the early diagnosis and treatment of GDM remained unclear. In this study, 60 patients with GDM were selected as the research group and 50 healthy pregnant women as the control group. Tumor necrosis factor receptor 1 (TNFR1), tumor necrosis factor-α (TNF-α), and adiponectin (ADP) in the serum were measured by enzyme-linked immunosorbent assays (ELISAs). The levels of fasting blood glucose (FBG), fasting insulin (FINS), and glycosylated hemoglobin (HbA1c) were also detected to calculate homeostasis model assessment insulin resistance index (HOMA-IR) and pancreatic β-cell function index (HOMA-HBCl). Compared with the control group, the serum levels of TNFR1, TNF-α, and HbA1c in research group were significantly increased ( P < 0.05), while ADP showed lower levels ( P < 0.01). Furthermore, FBG, FINS, and HOMA-IR were evidently increased ( P < 0.05), while homeostasis model assessment insulin secretion index (HOMA-β) and insulin sensitivity index (ISI) were decreased ( P < 0.05) in research group. TNFR and TNF-α were positively correlated with FBG, FINS, and HOMA-IR ( P < 0.05). In addition, there was a significant negative correlation between ADP and FINS and HOMA-IR ( P < 0.01). From logistic regression analysis, age, gestational age, FBG, FINS, TNFR1, TNF-α, and ADP ( P < 0.05) were shown to be risk factors to affect the function of islet β-cells. In conclusion, the high levels of TNFR1 and TNF-α and the low levels of ADP in the second trimester of pregnancy are the risk factors of GDM, which are related to the insulin resistance and impaired pancreatic β-cell function.

BACKGROUND Several surrogate estimates have been used to define relationships between insulin action and pancreatic β-cell function in healthy individuals. Because it is unclear how conclusions about insulin secretory function depend on specific estimates used, we evaluated the effect of different approaches to measurement of insulin action and secretion on observations of pancreatic β-cell function in individuals whose fasting plasma glucose (FPG) was &lt;7.0 mmol/L (126 mg/dL). METHODS We determined 2 indices of insulin secretion [homeostasis model assessment of β-cell function (HOMA-β) and daylong insulin response to mixed meals], insulin action [homeostasis model assessment of insulin resistance (HOMA-IR) and steady-state plasma glucose (SSPG) concentration during the insulin suppression test], and degree of glycemia [fasting plasma glucose (FPG) and daylong glucose response to mixed meals] in 285 individuals with FPG &lt;7.0 mmol/L. We compared the relationship between the 2 measures of insulin secretion as a function of the measures of insulin action and degree of glycemia. RESULTS Assessment of insulin secretion varied dramatically as a function of which of the 2 methods was used and which measure of insulin resistance or glycemia served as the independent variable. For example, the correlation between insulin secretion (HOMA-β) and insulin resistance varied from an r value of 0.74 (when HOMA-IR was used) to 0.22 (when SSPG concentration was used). CONCLUSIONS Conclusions about β-cell function in nondiabetic individuals depend on the measurements used to assess insulin action and insulin secretion. Viewing estimates of insulin secretion in relationship to measures of insulin resistance and/or degree of glycemia does not mean that an unequivocal measure of pancreatic β-cell function has been obtained.

Severe Falciparum Malaria

Insulin Resistance is a major factor among patients with critical illness due to various causes. Severe falciparum malaria with MODS diagnosed as per the criteria of MSS and admitted to the Medical ward of our hospital were assessed for IR and β cell function by using homeostasis model assessment. 75 consecutive patients of SFM admitted to the Medical ward of our hospital were included in this study. Malaria was diagnosed as per criteria of WHO and organ dysfunction was diagnosed as per Malaria Severity Score. Insulin Resistance and β cell function was assessed by using homeostasis model assessment on Day-1 and Day-7. Out of 75 patients of severe falciparum malaria with MODS 2, 3, 4, and 5 organ dysfunctions constituted 16 (21.3%), 34 (45.3%), 16 (21.3%), and 9 (12.0%) patients, respectively.Hepatic failure was the most common organ system failure (n=58; 77.3%), followed by neurological (n=50;66.6%) ,renal (n=40;53.3%), hematological (n=30; 40.0%), and, respiratory failure ( n=15; 20.0%). Hyperglycemia was present in 25 (33.3%) cases where as normoglycemia was present in 50 (66.6%) cases. The values of FBS, Tg, insulin, IR, and β cell function decreased on Day-7 compared to Day-1 after recovery from critically ill state. The patients who died had a high insulin value, IR, but low β cell dysfunction compared to the survivors. This study showed that IR and β cell dysfunction were associated with severe malaria with MODS with increased mortality.

Abstract Objectives In an aging population, an increase in the number of elderly cancer patients with cognitive impairment is expected. The possible association between cancer and cognitive impairment is important to elucidate, because it can have a serious impact on quality of life. Here, we focused on glucose metabolism as a factor that links cancer and cognitive impairment. Results Thirteen subjects with solid cancers and cognitive impairment were recruited. As a control group, 14 subjects with cognitive impairment alone and 8 subjects with cancer alone were recruited. A Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) and that of β-cell function (HOMA-B) were used. In comparison with patients with solid cancer alone, those with cognitive impairment alone and those with both cancer and cognitive impairment had increased HOMA-IR values. Insulin resistance was increased in patients with cognitive impairment alone and those with both cognitive impairment and solid cancer than in patients without cognitive impairment; however, β-cell function was not affected. The present data indicated that elderly cancer patients with high HOMA-IR score may be at a relatively high risk for developing cognitive impairment. Furthermore, early treatment to reduce insulin sensitivity may prevent cognitive impairment.

Background and aims: Many findings have shown the potential relation between osteocalcin (OCN) and regulating energy metabolism. In addition, it has been revealed that physical activity increases OCN levels. Therefore, the present study aimed to investigate the effects of different exercise trainings on β-cell function, insulin resistance, and OCN levels in overweight men. Methods: In this study, 33 overweight, young men [Body mass index (BMI): 29.32±0.75 and age range of 31.50±2.23] were randomly divided into control (n=11), aerobic exercise (n=11), and resistance exercise (n=11) groups. Participants of the exercise group were on the 8-week supervised exercise training program for three sessions per week. Weight, body fat percentage, and BMI were analyzed, and then OCN, insulin, and the homeostasis model assessment of insulin resistance (HOMA-IR) were assessed from fasting blood samples before and after the 8-week exercise program. Finally, data were analyzed by t test and analysis of covariance (ANCOVA). Results: Based on the results, BMI and body weight, insulin, glucose, and HOMA-IR reduced following the exercise (P<0.05) whereas serum OCN significantly increased in aerobic exercise (P=0.001) and resistance exercise (P=0.000) groups. There were no significant changes in β-cell function in aerobic exercise (P=0.512) and resistance exercise (P=0.16) groups. Pearson correlation analysis demonstrated that OCN levels were not correlated with HOMA-IR (P=0.743) and insulin levels (P=0.143). However, OCN was positively associated with the homeostasis model assessment of b-cell function (P=0.014) and glucose (P=0.025). Conclusion: The results of the present study confirmed that aerobic and resistance exercises cause some changes in body weight and BMI, as well as the OCN and HOMA-IR. Nonetheless, changes in OCN levels were not predictors of changes in insulin secretion from pancreatic beta cells.

Abstract Objective Secretagogin, a Ca2+ binding protein, is one of the most abundant proteins in pancreatic β-cells and is critical for maintaining the structural integrity and signaling competence of β-cells. This study seeks to assess the concentrations of plasma secretagogin in participants with prediabetes (pre-DM) and newly diagnosed type 2 diabetes (T2DM) and to explore its relationship to parameters of glucose and lipid metabolism, first-phase insulin secretion, insulin resistance and pancreatic β-cell function. Materials and Methods A total of 126 eligible subjects were divided into three groups: a normal glucose tolerance (NGT, n=45), a pre-DM (n=30), and a T2DM (n=51) group. An intravenous glucose tolerance test (IVGTT) was performed, and clinical and biochemical parameters were measured for all subjects. Results Plasma secretagogin levels were significantly higher in both pre-DM and T2DM patients compared with NGT subjects and were highest in the T2DM group. Correlation analysis showed that plasma secretagogin levels were positively correlated with fasting plasma glucose, postchallenge plasma glucose (2hPG), HbA1c and body mass index (BMI) but were not correlated with waist-hip ratio, blood pressure, lipid profiles, fasting serum insulin, homeostasis model assessment for insulin resistance, homeostasis model assessment for β-cell function and first-phase insulin secretion indicators. Multiple logistic regression analysis revealed that 2hPG and BMI were independent predictors for elevation of plasma secretagogin concentrations. Conclusions Increased circulating secretagogin might be a molecular predictor for early diagnosis of diabetes. Further studies are needed to confirm this finding and explore the role of secretagogin in obesity.
